Shanghai Joyal Mining Machinery Co., Ltd. sand making machine include vsi sand making machine and pcl sand making machine.

Introduction of Joyal vsi sand making machine

The JOYAL VSI Crusher is improved on the basis of Germany high technology, which is highly-efficient and superior in performance. The JOYAL VSI Crusher (sand making machine) is widely used to produce sand and stone for highway, high-speed railway, city project, hydropower dam constructions, and concrete mixing plant, and it’s also widely used in sand making and stone reshaping industry.

1. the oil needed is supplied by two oil pumps, and the machine stops automatically if there is no oil; the motor can be heated automatically in winter to ensure the normal working of the machine.
2. Hydraulic lifting system to check and replace the spare parts, thus it’s very easy and simple to maintain.
3. the bearing is of SKF and TIMKEN brand to ensure the normal working of the machine.
4. unique vibrating alarm device: if the machine works abnormally, the alarm will sound to stop the machine, thus protecting the whole machine.
5. Special feeding structure; rock on rock, and rock on iron to make the stones crushed and reshaped.
6. Unique dustproof seal system to prevent the dust getting into the spare parts.
7. unique design of material bumping angle reduces the friction between raw material and spare parts, extending the working life of spare parts and cut the cost.

1. Central feeding:Raw materials fall down into the feeding hopper, then enters the impellor through central entrance inlet, thus the material being accelerated by the high-speed impellor and being thrown out at the speed of 60-75m/s. It is crushed when hitting the impact plate, and the end products comes out from the discharging outlet.
2. Ring feeding:Raw materials fall down into the feeding hopper, and the materials are divided into two parts by a special plate. Some materials enter the impellor through the center of the plate and the other part of materials falls down from outside of the plate. The materials thrown out earlier crush the materials down from outside, thus the materials crushed and re-crushed.

Intrduction of Joyal pcl sand making machine

The JOYAL PCL Vertical Shaft Impact Crusher is widely used for fine crushing and coarse grinding in mining, rocks, fireproof materials, glass raw material and metallurgy residues. The impact crusher is much more professional than other crushers in crushing hard and anti-abrasion materials such as carborundum, sintered bauxite, magnesite and so on. The Impact Crusher is usually used as sand making machine in the sand washing plant.

1. Simply structure and low investment.
2. High efficiency and low
3. Scaleboard of the impeller is easy in maintenance and durable.
4. Appliable to fine and coarse grinding.
5. Slightly influenced by the moisture content of the material. The max moisture content is 8%.
6. Suitable for crushing materials of middle and high hardness.
7. Cubic shaped end products, high density of piling up and low iron pollution.
8. Working noise < 75db, and little dust pollution.

The materials fall into the crusher and be divided into two parts. One part goes into the high-speed-running impeller of the machine, and the other part goes around the impeller. The two parts materials bump into each other at a high speed and are crushed in this way under the centrifugal force. The end products go out from the bottom of the machine, and users can get the required products size after materials are screened by the vibrating screen.
